This is an overall quality/style/value review. If you've had other folding reading glasses, you have probably dealt with those that were pretty flimsy, and/or overly small. Where the company traded quality materials and style to give you something small-ish. That's not the case here.Quality: These feel sturdy with substance instead of very light weight metals. The screws seem to be doing a solid job as opposed to just a pivot point for everything to just swing around freely. In fact, I kind of hope they loosen up a little but with time, but I like that they hold together so well.Style: My biggest complaint with other folding glasses is that they don't look like regular glasses. Some are so narrow that it's hard to focus you eyes on the actual glasses. Once unfolded, these look like full glasses. Maybe a little closer to reading glasses, but I can wear them up close OR down on my nose. Either is comfortable and allows me to read easily.Value: 15 bucks for 2 pair? Seriously, you probably have a pretty low expectation for what these will be at that price. Since I only wear glasses for reading, I have bought more than my share of Walmart glasses to keep around the house, and these are better than any of those I have bought. These are my "going out" readers. Something my wife will keep in her purse (size), and I'm not embarrassed to wear in public (style). That's good value in my book.As with any folding glasses, i can't imaging they are made for heavy use. Any thing with moving parts has a limited lifespan. The more you move those parts, the more wear on the screws/joints. However, as occasional readers, they are great. I will use these for menus eating out, and great travelers away from home. I'll keep my real cheapies for every day reading around the house.
